If P is 60% of Q, Q is 50% of R; R is 40% of S, S is 45% of T. Find P: T ?

OPtion

1) 3/50
2) 3/25
3) 7/50
4) 8/25
5) 4/25
6) 27/1000
7) 27/250
8) 27/500
9) 27/2000
10) None of these

Solution

P = 0.6 Q
Q= 0.25 R
So P = 0.6*0.25 R
R = 0.4 S
So, P = 0.6*0.5 * 0.4 S
S = 0.45*T
Again, P = 0.6* 0.5 * 0.4 * 0.45*T = 54/1000T
So P/T = 27/500
